For quick documentation see: https://github.com/kubaPod/M2MD/wiki
Simple converter of Mathematica notebooks to markdown.

ResourceFunction["GitHubInstall"][ "kubapod", "m2md" ]
Go to 'releases' tab and download appropriate .paclet file.
Run PacletInstall @ path/to/the.paclet file
If you don't have MPM` yet, run:
Import["https://raw.githubusercontent.com/kubapod/mpm/master/install.m"]
and then:
Needs @ "MPM`"
MPM`MPMInstall["kubapod", "m2md"]
From now on there should be a M2MD item in your Palettes menu.
